To remove the media services card (MSC)

Warning: Protect the hardware components against damage from electrostatic discharge. Always wear a grounded wrist strap before you handle components. Always place the components in a static-free container.

Note: If you purchased optional BCM applications that require keycode activation, regenerate the keycodes after you install the replacement MSC. For further information, see “Software keycode” on page 181 and “To install the media services card (MSC)” on page 306.

Note: If you need to install a new MSC, you must upload new core software from the hard disk. See “To install the media services card (MSC)” on page 306.
